Ultrasound is above 18 kilohertz.
Infrasound is below 20 hertz.
Infrasound is always smaller or lighter than ultrasound. For example: infrasound can be the sound of a paper clip hitting the floor, and ultrasound can be the sound of two planets colliding.
Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above the range of human hearing (above 20 kHz). Infrasound is used in monitoring seismic activity and animal communication, while ultrasound is used in medical imaging, industrial cleaning, and pest control.
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
Infrasound has longer wavelengths compared to ultrasound. Infrasound waves have frequencies below the range of human hearing (below 20 Hz), while ultrasound waves have frequencies above the range of human hearing (above 20 kHz), leading to their differences in wavelength.
Ultrasound and infrasound differ in their frequencies and applications. Ultrasound has frequencies above the range of human hearing, typically above 20,000 Hz, and is used in medical imaging, cleaning, and industrial processes. Infrasound has frequencies below the range of human hearing, typically below 20 Hz, and is used in earthquake detection, monitoring volcanic activity, and studying animal communication.
No, but you can use ultrasound to clean glassware.
The opposite of ultrasound (above the human hearing range) is infrasound (below the human hearing range).
Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Ultrasonic waves have frequencies above the audible range at around 20 kHz. Audible sound is within human hearing range.
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
Ultrasound.
I beg your pardon? Sound is not a person, let alone a living being. >:-(
Sound below 20Hz is considered infrasound, while ultrasound typically refers to sound frequencies above the human hearing range (above 20kHz).
